Create new php website from existing template

Hi Guys, Small task: We found a html template which we like. We need to convert i to a php website, with backend. Joomla? The website backend should have an excel upload function. We need to upload an excel file (SQL) containg about 5-6 columns. Its output is a dropdown menu on website. Not too difficult. Urls should be static (though php), optimized for SEO. Metatags and everything should be available and editable by me in back-edn.. We already have an excel upload function on current website, so if too difficult we can copy the php file from there. easy task. We have a lot of work on other websites, so if you deliver good work, we may stick with you for future mods. Current webdesigner too busy with out other tasks. thanks
